This type of roof is typically less costly to build than the sloped alternative. They are fairly easy to access and the latest versions are made of a material that reduces the amount of heat absorption, together with providing enhanced protection from leakage.
One of the most revolutionary and fastest-growing roofing products in the commercial sector is TPO. Thermoplastic polyolefin is a single ply membrane that is renowned for its performance and durability. As more clients are choosing energy-efficient roofing systems and heat reflective properties TPO single ply roofing membranes are becoming more popular. They provide outstanding resistance to ozone and chemical exposure, as well as ultraviolet rays.

Another alternative is the polymer- modified bitumen sheet membrane. This type of product has reinforced fabrics and is typically installed in multiple layers. The bitumen is made of reinforced polyester fiber matting or fiberglass, to make it much stronger and more durable.
Polymer modified bitumen sheets have the advantage of being weather resistant, very durable, fairly easy to install and easy to repair. They can put up with a variety of different weather conditions due to their flexibility and ability to expand and contract with different temperatures.

Customers can choose between two different types – APP and SBS. The latter is the most flexible of the two and has enhanced contraction and expansion capability. The former is more durable and increases the life expectancy of the roofing system. It is also the most popular of the two.
